I have heard good things about the mx518 and the g5....

My i.e 3.0A manages to stop working now and again due to me mucking about with the polling rate.... Warning i.e 3.0A users :P
The one i got from softpedia that changes hz managed to fuck up my mouse.

So my question to you lot is....

g5 or mx518??

There is questionable build quality for the g5 though.... also the g5 seems to be overpriced in the places i have looked.

Or just get another i.e 3.0A. Trouble is i have looked and can't find the exact silver slimline 5 button one that i have been using. The ones on ebay appear to have chunky forward and back buttons...
